GENERAL DESCRIPTION  
The ADR42x are a series of ultraprecision, second generation  
eXtra implanted junction FET (XFET) voltage references  
featuring low noise, high accuracy, and excellent long-term  
stability in SOIC and MSOP footprints.  
Patented temperature drift curvature correction technique and  
XFET technology minimize nonlinearity of the voltage change  
with temperature. The XFET architecture offers superior  
accuracy and thermal hysteresis to the band gap references. It  
also operates at lower power and lower supply headroom than  
the buried Zener references.  
ADR425: 7 V to 18 V  
Quiescent current: 0.5 mA maximum  
High output current: 10 mA  
Wide temperature range: −40°C to +125°C  
APPLICATIONS  
Precision data acquisition systems  
High resolution converters  
Battery-powered instrumentation  
Portable medical instruments  
Industrial process control systems  
Precision instruments  
The superb noise and the stable and accurate characteristics  
of the ADR42x make them ideal for precision conversion  
applications such as optical networks and medical equipment.  
The ADR42x trim terminal can also be used to adjust the out-  
put voltage over a ±±.ꢀ5 range without compromising any  
other performance. The ADR42x series voltage references  
offer two electrical grades and are specified over the extended  
industrial temperature range of −4±°C to +12ꢀ°C. Devices have  
8-lead SOIC or 3±5 smaller, 8-lead MSOP packages.
